thanks - yes i do see those in string output window within admin of BatteryView, and the value of 148000mA is equivalent of 4x37,5A recommended charge and discharge rate of my us3000a - it might be my growatt that is not very stable then. had the batteries working fine with a mpp inverter. Update:; i got a firmware update for my growatt sph3600 - and now everything seems to work.

I tried to downgrade my us3000a to 2.8.. but i still do not have a charge and discharge advise in batteryview.. is there any place this setting can be set? it might be my growatt that is not working proberly, but for now i would see is i can rule out the pylontechs ( i have 4) and my growatt set above 600w of charging (around 20%) fails to charge batteries. in batteryview i do get a message in string output that says: recommended chg current: 148000 mA recommended dsg current -148000 mA

Hi purepower.. i have the same issue as no charge current and discharge current is present in my battery view screen.. and i have some issues with a growatt sph that cycles up and down in chage and discharge current, i suspect it cant read the setting of max charge and discharge current too.. can i ask for the admin pass too so i can set max allowed ? thasnks

Hi randmetal. Did you get to downgrade your batteries and have batteryview advise both charge and discharge current? i have a similar problem with 4 us3000a and wondering if a downgrade could be the solution (my growatt sph3600 fails when charging with more than 600w.. and cycles up and down in discharge rate)

Interesting, i have never discharged my batteries below 15% to keep them somewhat fresh.. my own logic will charge to 25% when 15% is reached. I will keep an eye on my batteries if they will go to 100% again. my weather report though says that the following days will be some what sunny, so the batteries will get charged. i can see we had at least 3 weeks with almost no sun until yesterday

I could not by sending any commands to the mpp by solpiplog do anything with any settings to change to either SBU og Solar only charge until the battery was at 100% i was allowed to change to 20amp or 30amp charge, but if i choose 2amp, it would stay at 10amp grid charge.

ICC is not installed, only solpiplog, with a logic beeing controlled from noed red and mqtt, and no change of amp charge settings here. Ive seen the pylontech change max charge of amp from solar, with two batteries this is fixed to 70amp, and this i cant change. But i hear you Coulumb, this is not a behaviour i suspected. I have a enapter device on the serial port, this one i do not know much about yet - it might have done something, but when i saw this morning that the mpp was charging my batteries with 10 amps, it still reported max 2 amps in solpiplog as max charge from utility.

The Pylontech choose to charge to 100% today, after 3 weeks with no or little sun, the charged have been kept around 20-25% - but today the Batteries choosed to go to 100% with charge from grid, even thought the 5048mk is set to max allow 2amps charge, it was like this was override and the pylontech was charged with 10amps. Anyone know if the pylontech will initiate a 100% charge after some time not beeing charged fully?

for long time i wanted an ac unit.. now that is more interesting, i could set it to start at 90% SoC and then draw the power from the panels to the AC unit instead of charging the batteries.. it could run from 90% SoC to lets say 60% SoC, then i would still have enough battery to get through the night on my other appliances hooked up to the battery. Now i just need to find an AC unit i can control by MQTT 😄

ahh yes. right now my inverter is set to PYL 05 setting, so i am pretty sure i am not allowed to change charge current and voltages. then i have to set it to USER settings to do that, but then i will loose my SoC rading, which is presented by the Pylon batteries through my inverter atm. luckily we have not much sun in Denmark right now. so i will not get a 100% charge before march anyway. when the SoC reads 100% i can see the inverter stops charging. and only holds the voltage steady. by reading through my watt meter on the Victron BMV only a little wattage goes to the batteries.

Thanks Coulumb. i think i need to figure out how to stop charging at 95% SoC then, i cant find a setting in the menu where i can choose this. Any1 with an idea to this? maybe i can set it up in the bms for the pylontech?

Hi forum. My first post, have a user mostly for downloading firmware for my MPP 5048 MK for which i have connected two Pylontech US3000 batteries. Which report SoC to my inverter. ive made a logic with mppt via solpiplog, and was wondering which SoC i can go to at the lowest on the pylontech batteries. Right now my logic is as in attached picture. Short;: change to grid charge at 10%, Change back to Solar charge at 15%, Change to ECO (Bypass mode) at 20% and lastly go to battery mode at 25% i will only use the Grid as backup. But can i go as low as 1% Soc before i do this? i mean is, the SoC reported from the batteries safe to use between 1-100% SoC or should i stay between lets say 10-100% ? I hope you guys understand my question, i will use settings to keep the condition of my batteries as best as possible. If you have any other suggestion feel free to add to my post. Thanks
